METHOD FOR MAKING GUTTER ENDS.

Original application filed May 25, 1922, Serial No. 563,626. Dividedandthis application filed December To all whom it may concern:

Be it known that I, THOMAS RIGBY, acitizen of the United States,residing at Philadelp hia, county of Philadelphia, and State ofennsylvania, have invented a new and useful Improvement in Methods forMaking Gutter Ends, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform apart of this specification.

This invention relates to a. method of making'gutter ends, or endsforeaves troughs.

The object of my invention is to provide a method for making ends ofthis character which are uniform, which can readily be applied to theends of troughs or gutters without first separating the trough receivingelements, and which may be driven into posi tion to form tight jointswithout soldering.

The precise nature of my invention will best be understood by referenceto the accompanying drawings in which is illustrated a gutter end madein accordance with my invention and views illustrative of various stepsin its production, it being understood that various changes may be madewithout departing from the spirit of my invention as defined in theappended claims.

Fig. 1 is a perspective view of one form of end made in accordance withmy invention.

Fig. 2 is a plain view thereof.

Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

Fig. 4 is a view, similar to Fig. 2, showing a gutter end, in positionon a trough.

Fig. 5 is an end View thereof with the trough in sections.

Fig. 6 diagrammatically illustrates the various steps in the formationof the ends.

The gutter end shown in the drawings comprises an end member a ofsemi-cylindrical form, having an integral arcuate flange Z2, slightlyflared. The gutter end is also provided with an inner arcuate flangemember 0 adjacent to the flange b. This flange member 0 is secured inposition by a radially disposed flange along one edge thereof which issecured within an arcuate head (i formed of members extending from theend a and flange Z). The flange member 0 is substantially normal to theend a, while the outer portion of flange member 7) extends at an anglethereto, so as to form a Serial No. 604,720.

tapered recess between the flange members I) and 0, as clearly shown inFigs. 1, 2 and 3.

I preferably form the flange member 0 normal to the end member a, aswell as somewhat longer than the flange "member I). v

home on the end of a trough.

When applying a gutter end to a gutter or trough which has beenpreviously shaped as shown at e in Figs. 4 and 5, the

end of flange memberd which extends be-v yond member 6 is laid withinthe trough,

and the trough end is pushed longitudinally relative to the trough,until the "trough is.v

well seated between flange members 6 and The trough end is then gentlytapped along the bead (Z to firmly wedge the end of the trough 6 betweenthe flange members I) and c. As the flange member 0 is parallel to thetrough e and the inner face of the trough is forced against the outerface of flange member 0 by the wedging action, a water tight joint willbe formed between these faces, without soldering.

When it is desired to remove an end or replace an end with a new end,the end can readily be removed from the trough by tapping, withoutinjury to either the end or trough.

1n the manufacture of the ends such as shown, blanks of substantiallysemi-cylindrical form are first died out, a section of a portion of onebeing shown at f in Fig. 6. The blanks are then placed between dies toform a. deep arcuate flange thereon as shown at g in Fig. 6. The flangedblanks are then placed between drawing dies and an arcuate head isformed, with an arcuate recess between the bead forming members as shownat h in Fig. 6. The beaded blanks together with narrow strips of sheetmetal are assembled as shown at 2' in Fig. 6, and are assembled in diessuch as shown in Fig. 7. The dies are then closed about the assembledblanks to roll the bead inwardly and bend a flange on the insertedstrip, which forms flange c and secures said flange in position as shownat 9' in Fig. 5, and thus completing the article as shown in Figs. 13.

The advantages of my invention result from the provision of a method offorming gutter end having two flanges extending therefrom, arranged toreceive the end of an eaves trough or gutter between them, one of theflanges extending at an acute angle to the other whereby a taperedrecess is formed to permit wedging the trough between them and form atight joint without,

the use of solder, and in' which the mouth of the recess is ofsnflicient Width to readily permit the entrance of the trough.

This application is a division of my application Serial No. 563,626,filed May 25, 1922.

Having now fully described my invention, what I claim and desire toprotect by Letters Patent is:

1. The method of making gutter ends having an end member and two flangeseX tending at substantially right angles thereto with a flared gutterreceiving space between them, comprising assembling par-- tially shapedgutter end forn'nng members, maintaining the outer free ends of theflange forming members spaced from each other and simultaneously forminga bead at the junction of the end member and the flanges, and forcingthe flanges into engagement with each other adjacent to the bead to forma' -tapered groove between the flanges.

2. The method of making gutter ends vhaving two flanges extending froman end flanges, comprising the steps of assembling a flanged blank and aflange forming strip, forming a bead at the junction of the flange andthe end forming portion of the flanged blank and simultaneously foldingwithin the bead one edge of the strip, and during the forming of thebead maintainingthe free edges of the flanges separated to form atapered recess simultaneously with the beadmg;

3. The method of making gutter ends of semi-circular form having twoarcuate flanges extending therefrom with a flared recess between them,comprising the steps of forming a blank with a semi-circular end member,an arcuate flange extending from the arcuate peripheral portion thereofand an arcuate groove in a head between theflange and the body, placingan edge portion of a flange forming strip in said groove, holding theother edge portion of the said positioned flange forming strip free ofthe outer portion of the flange, and simultaneously rolling over a beadand forcing the flange forming member and flange into engagement witheach other adjacent to the end member while holding the free edgeportions of the flange and flange forming strip separated.

In testimony of which invention, I have hereunto set my hand, atPhiladelphia, Pa. on this 29th day of November, 1922.

THOMAS RIGBY.
